Specification of Letters Patent.

Patented Feb. 24, 1914.

Application filed August 6, 1912. Serial No. 713,673.

To all whom it may concern Be it known that I, PIETRO RINDONE, a subjectof the King of Italy, residing at Los Angeles, in the county of LosAngeles and State of California, have invented a new and usefulChimney-Cap, of which the following is a specification.

This invention relates to a cap for chimneys and the main object of theinvention is to provide a cap which will maintain the natural draft ofthe chimney under all conditions of weather so that the draft will notbe interfered with by rain or wind.

A. further object of the invention is to provide for removability andreplaceability of the several parts of the chimney cap.

Other objects of the invention will. appear hereinafter.

The accompanying drawing illustrates an embodiment of the invention andreferring thereto :-Figure 1 is a vertical section of the chimney. Fig.2 is a transverse section on line na -00 in Fig. 1, with a portion ofthe supporting cage for the deflectors broken away.

1 designates the chimney on which the cap is placed, said chimney havingthe flue 1 which is generally rectangular in cross section. A cage 2 isplaced on said chimney, said cage having a bottom plate 3 which isrectangular in shape and provided with a central opening 4 registeringwith the chim ney fine, and said cage being provided with vertical bars5 at the respective corners for supporting a top plate or frame 6 whichis provided with a central opening 6. An inner deflector member 7 isprovided having at its top an outwardly extending horizontal flange 9adapted to rest on the top plate 6 of the cage, said deflector alsohaving a clowntapering portion 10 formed as an inverted pyramid whichextends downwardly within the cage 2 and into the chimney flue 1, thefaces of said pyramid being opposite the respective lateral openings 12in the cage between the vertical bars 5. A hood member 14 is providedhaving upwardly converging side walls 15 formed as faces of a truncatedrectangular pyramid and said hood member being provided with inwardlyextending ribs 16 which rest on the bottom plate 3 of the cage tosupport the hood member in position. The top member 18 is provided witha bottom plate 19 resting on top of the deflector member 7 and of suchdimension as to leave a slot or opening 20 between said plate 19 and theouter walls of the hood member 14. Said top member 18 may be providedwith upwardly extending flanges 18 for supporting any desired ornamentaldevices 21, including for example, a weather vane 22. The chimney 1, cap2 and deflector members 7 and 14 and top member 18 are preferably ofterracotta or similar material, each of said parts being molded in asingle, separate piece, so that the entire construction can be quicklyand readily assembled or taken apart.

The operation is as follows :The hot gases ascending from the fine 1'are deflected by the inverted pyramid 10 and pass outwardly through theopenings 12 and up within the hood 14, escaping finally through thespace 20 at the top of the hood. Any rain which falls on the cap cannotfind its way into the chimney as it is deflected by the top member 18and the hood 14, and any wind blowing on the chimney cap is deflected bythe hood 14 so that it does not interfere with the natural draft, whileat the same time the course of the hotgases from the fine is almostdirectly upward so that the deflectors do not interfere with theintensity of the draft.

VYhat I claim is In combination with a chimney, a cap thereforcomprising a cage member having a bottom plate adapted to rest on thechimney and having a central passage, said cage member being providedwith vertical bars at the respective corners and with a top plate havinga central opening, an inner deflector member in the form of an invertedpyramid extending downwardly within said cage member and having ahorizontal flange resting on the top plate of the cage member, a hoodmember having its walls converging upwardly from bottom to top in theform of a truncated pyramid and provided with in- In testimony whereof Ihave hereunto set wardly extending ribs resting on the bottom my hand atLos Angeles, California, this plate of the cage member, and a top member1st day of August 1912.
